Dear [Friend's Name],
I hope this letter finds you well. I am currently on vacation in [destination]. The weather here is beautiful and there are so many fun things to do.

The food here is also delicious. I tried some local dishes such as [dish name] and they were absolutely delicious. I wish you were here to taste them with me.
I miss you so much and I can't wait to see you when I return. Please take care and write back soon. Give my regards to your family.
